Specification of Letters Patent.

Patented July 16, 1912.

Original application led March 26, 1904, Serial No. 200,160. Divided andthis application filed October 26,

To all whom it may concern:

Be it known that I, WILLIAM F. PURGELL, a citizen of thepUnited States,residing in New York city, borough of Brooklyn, county of Kings, andState of New York, have invented certain new and useful Improvements inBrushes., of which the following is a full, clear, and exactspecification.

My invention relates to certain new and useful improvements in brushesand the manufacture thereof, and has for its vobject the production of acheap and durable brush wherein the bristles are securely held bymechanical means, thus avoiding the necessity of using cement or otherlike substance, while producing an efficient and valuable article.

This application is a division of a pending application filed by meMarch 26, 1904, Serial No. 200,160, wherein the present invention wasdescribed and claimed.'

In the drawing, Figures l, 2, 3, and 4 indicate specic forms of myinvention and are sectional views showing the handles, bristles, andsecuring means in their assembled positions.

In the figures, A represents the handle, i3 the bristles, and C acylindrical ferrule having an annular depression or recess therein. Theferrule is preferably made of metal and is designed to be fixed to t-hehandle byany suitable means well known in the art. For

example, in Fig. l, the upper' end of the ferrule C is crimped orpinched around a shoulder on the handle so as to hold the same inposition. In Fig. 2 the ferrule C internally threaded and is screwed onto the handle A in a well known manner. In the construction illustratedin Figs. 3 and 4, the ferrule is held on the handle by friction or othersuitable fastening means well known in the art. It will be observed thatin each construction shown in the drawing t-he lower end of the ferruleC forms an annular depression intoY which the upper ends of the bristlesare fitted.

The upper end of the bristles is inserted within the ferrule and afloating core or ball D is located in the center of the bundle ofbristles, and in connection with the ferrule serves to hold the bristlessecurely in place. The upper ends of the bristles eX- Serial No.340,621.

tend above the floating core and thus are clamped both above and belowthe core.

The method of making the brush which I prefer to employ is first,inserting the bristles within the sleeve or ferrule, then inserting thefloating core or ball substantially in the center'of the bundle of thebristles and about midway of the ferrule; then pressure is applied tothe outside of the ferrule and its lower end is contracted, and in thecase of Figs. 3 and 4 the upper end of the ferrule is also contracted;by which means the bristles are uniformly clamped between the ferruleand the floating core and thus securely held in place.

In the construction shown in Fig. 4 the ferrule C preferably is formedin twosemicircular sections which are suitably secured together by meansof a central ridge formed by bending the material of one section arounda flange on the other sect-ion as clearly illustrated.

In Figs. l and 2 slight modifications have been shown, wherein theferrule is not contracted at its upper end, but an extension of thehandle is pro-vided with a contracted portion. In the manufacture ofthis style, all that is necessary, after the ferrule has been secured tothe handle, is to insert the bristles in the ferrule, insert thefloating core, and then by means of suitable pressure apparatus,forcibly contract the lower end of the ferrule around the bristles, whenthey will be firmly locked in place, as shown.

Having thus described my invention, what I claim and desire to secure byLetters Patent is:

l. In a brush, the combination with the handle, the bristles and aferrule having an annular depression, of a ball within said ferrule andsurrounded by said bristles, substant-ially as described.

2. A brush comprising a floating core, bristles disposed about it, and acontinuous integral metal sleeve surrounding the bristles and contractedthereupon to clamp them in bristle chambers in said sleeve both aboveand below the core.

3. A brush comprising a fioat-ing core, bristles surrounding it, a metalsleeve enveloping and confining the bristles, a handle disposed in theaxial line of the brush, and
